I don't agree if you say Pochettino will not be burdened by Chelsea's demands. Pochettino has signed a contract to do his job of reclaiming the glory left for Chelsea in recent seasons. He has to take responsibility for the job he chooses to do, so obviously that will be the weight Pochettino is most likely to think about during his stay.
Chelsea supported him with a budget and smoothed out his development plans by selling several senior players. This team has been very different and there is no certainty whether Pochettino will succeed in a few seasons or maybe he will suffer the same fate as Tuchel, Graham Potter and Lampard.
Surely there will be stronger pressure from Chelsea management on Pochettino next season. Because last season Chelsea did not display its best form as a big team in the Premier League, so it is hoped that his presence as the new Chelsea coach will bring Chelsea back into a strong team next season. Now seeing the big shake-up Chelsea have done in this transfer window I'm not too sure they will be stronger next season. Chelsea haven't made many big signings in this season's transfer window due to having a large stock of the players they brought in in last season's transfer window.
So Chelsea last season were really weak in their defense and front line. But so far there have been no players to be positioned as attackers that they managed to bring in. If they fail to make any changes up front, then their form may be even worse compared to last season.
Undoubtedly, there would be a lot of expectations from Chelsea management and club fans on Mauricio Pochettino come next season because of the fact that he knows how to turn an average team to a very competitive just like he did with Tottenham Hotspur.
However, I don't think the club's management board would want to put too much pressure on him. Pochettino would be given time to build Chelsea to a very strong club that'll will be very competitive in not just domestically but also in Europe
